2 x^{2} - 8 x - 10 = 0

x = 5, x = - 1

Solution steps

2 x^{2} - 8 x - 10 = 0

Move

10

to the right side

2 x^{2} - 8 x = 10

Divide both sides by

2

\frac{2 x ^{2} - 8 x}{2} = \frac{10}{2}

x^{2} - 4 x = 5

Rewrite in the form

(x + a)^{2} = b

(x - 2)^{2} = 9

For

the solutions are

f (x) = a, - a

Solve

x - 2 = 9 : x = 5

Solve

x - 2 = - 9 : x = - 1

The solutions to the quadratic equation are:

x = 5, x = - 1

x^{2} - (m + n) x + mn = 0

x^{2} - x + \frac{1}{4} = 25

9 r^{2} - 25 = 0

2 (2 x - 5) - x^{2} + 17 x = 16 \cdot 4

5 x (x + 1) = 15
